HOT-AIR APFARATUS.

Specification of Letters Patent.

Patented July 29, 1913.

Application led February 14, 1912. Serial No. 677,594.

To all whom t may concern:

Be it known that we, VITO G. Fiisricor and MICHELE FAsrIGGI, citizens ofthe United States, residing in the city of New York, county of New York,and State of New York, iave invented new and useful Improvements inHot-Air Apparatus, of which the following is a specification.

This invention relates to improvements in hot air apparatus andparticularly t0 that class adapted for use in connection with kitchenstoves and ranges, and its objects are First, to provide devices for theeconomical conservation of heat, derived from consuming fuel conveyingany excess to remote apartments in which it may be desired to raise thetemperature. Second, to provide such apparatus in forms adaptable to anystyle of house range, whether builtin or self contained, in which isused any kind of fuel, as coal, wood, oil, or gas. Third, to providemeans whereby fresh air, preferably from an outside source, may bethoroughly heated and delivered free from any odors or gases arisingfrom the customary use of the range and without interfering with any ofits functions, or with its draft. l

Other objects, such as moderate cost of construction, non-liability ofdisorder, utilization of unoccupied space, ornamental appearance and thelike, will become more fully apparent in the following specification andare also indicated in the annexed drawings, in which y Figure 1 is afront elevation of the apparatus, parts being broken away showing theinterior. Fig. 2 is a. sectional elevation taken on line 2-2 of Fig` 1.Fig. 3 is a perspective view looking from the rear. Fig. 4 is a partialtransverse sectional view taken on line 4wd of Fig 1 and, Fig. 5 is apartial plan view of a range, parts being broken away showing theinterior, and section of the apparatus taken on line 5-5 of Fig. 1.

The device comprises a pair of stationary,

hollow cast or sheet metal standards 10 and in alinement with and.midway between these standards is a similar third member 11, all ofwhich are rigidly secured on the top of a range 12 at its rear, theouter standards being at the ends o f the range and so disposed as notto conliict or interfere with the free use of the range openings or withoperating the lids when supplying fuel or manipulating cooking utensils,the smoke and other products of combustion passing away through the pipe13 arranged in the usual manner.

An air pipe 14, having its inlets 15 preferably extending out 0f thebuilding so that pure fresh air may be obtained, enters the centralstandard 11 at the lower end thereof; the air passes through hollowtrunnions 16 t0 the heating chambers 17 and outwardly therefrom throughsimilar trunnions 18 to the outer standards l0 which are connected bythe heat diffusing chamber 19, the latter serving as a bridge betweenthe outer standards 10 and also is secured to the central standard 1l.

From the heat diffusing chamber l), which is provided with doors 20 sothat the saine can be used as a warming oven, the heat is conducted awayby distributing ducts 21 provided with dampers (not shown) to controlthe current of hot air passing through on its way to such points as maybe desired.

Returning to the heating chambers 17 it will be noticed that each ispivotally mounted between the outer standard 10 and the central member11 upon the trunnions 16 and 18 in such manner as to swing clear of theheatdiffusing chamber 19 and are adapted to be swung forward anddownward until they rest upon the t-op of the range; this operation isassisted by the counterbalancing weights 22, attached to the chains orcords 23 running over the sheaves 2-t and connected to the rear wall ofthe heating chambers. These chambers are provided with partitions 27 and26 attached at their ends alternately to the top and bottom wallsforming compartments but leav ing a clear space at their unattached endsin such manner that the entering air current is caused to travel fromone compartment to CIK another and to be subjected to heat derived fromthe range in its passage through the chambers. There is also provided anauxiliary heating chamber 27 adapted to be disposed within the main oveno-f the range which may be on either side of the fire-box; this chamberis similarly provided with partit-ions 28 and 29 for the same purpose asbefore described; it is also arranged with slip joints 30, which passthrough openings made in the rear walls of the oven and connect with atee 3l attached to the cold air inlet pipe and also with the standards10 as indicated at 32.

When the oven is required for other pur- Y poses, as cooking, theauxiliary chamber may be withdrawn, a handle 33 being provided for thatpurpose, and the openings to the air connections may be covered byswinging plates or dampers 34. Thus it will be seen that the arrangementis highly economical, no extra fuel being consumed and also that thedevice supplies heat in the same manner as a house-heating furnace butwithout its attendant expense and trouble.

It will be evident that the heat derived from burning fuel, that hasbeen hitherto wasted or worse than wasted by over heating the room inwhich the range is situated is, by this apparat-us, conserved and madeto effectively raise the temperature in other rooms than that in whichthe apparatus is placed.

Having thus described our invention what we claim as new and desire tosecure by Letters Patent, is:-

l. In an apparatus of the class described, in combination with a range,a chamber pivotally supported over the range, partitions extendingpartially through said chamber attached at their ends alternately to theupper and lower walls of said chamber so that a tortuous air passage isformed therethrough, means for admitting air into said chamber, a secondchamber horizontally disposed over the first named chamber, hollowstandards for supporting said` second chamber affording an air passagebetween the first and second chambers and iues leading from the lastnamed chamber tical supports for said chamber at each end thereof, adistributing` chamber communieating with said circulating chamberthrough said hollow supports, means for air entrance to said circulatingchamber and air ducts leading from chamber.

said distributing,f

3. In an apparatus of the class described, in combination with a range,a hingedly mounted air circulating chamber arranged to swing outward anddownward upon the top of said range, hollow supports rigidly mounted ontop of the range on each side of said circulating chamber and having airpassages providing communication between said chamber and supports,partitions within said chamber adapted to cause a circulation of airtherein, an air inlet communication with said circulating chamber and anair outlet from'said hollow support.

4c. In an apparatus of the class described, in combination with a range,air heating chambers pivotally mounted over the range to swing over andrest upon the top thereof, hollow supports at the sides and between saidchambers, tubular trunnions connecting said supports to said chambers,an air distributing chamber connected with the side supports over saidheating chambers, Vand an air inlet communicating with said heatingchambers, through the inner support, means for causing the air to passcircuitously through said heating chambers and air outlets combined withsaid distributing chambers. 1

5.
